TJ gears

Hi,



When a newer TJ (4-cyl?) comes with a 4.10 ratio Dana 44 rear with track-lock, is it true that the carrier is the same size as the one that would come with 3.73 ratio? In other words, is the factory 4.10 ring gear thicker than a typical 4.10 ring gear in order to compensate for the lack of a carrier break in the TJ Dana 44?



I've heard that the use of thicker 4.10 ring gears in order to avoid a carrier break in the TJ dates from the 1999 model year. Can anyone confirm this?



Thanks,



Steve

Hi Bill,

Are you sure about that? The Rubicon TJ uses a thick 4.09 ring gear on the 3.73-sized Tru-Lok:

Granted, the Tru-Lok is not a Dana carrier. While looking for some used

4.09 gears to fit my Tru-Lok, I found a set from a 2001 TJ D44 track-lock that the seller says will fit a 3.73 carrier. Just trying to confirm they'll fit before I mail away for them.

Is it possible that DC chose at some point to use thicker 4.09 gears in

4-cyl TJs in order to use up some 3.73-sized track-lock carriers?
